STAGE--SHADOWGRAPH.

Specification of Letters Patent.

Patented July 16, 1918;

Application filed November 6, 1917. Serial No. 200,505.

To all 'whom t may concern Be it known that I, GEORGE G. LONG, citizen of the United States, residing at San Francisco, in the county of San Francisco, State of California, have invented a new and useful Stage-Shadowgraph, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a device for producing shadow pictures of various kinds of objects upon a screen for theatrical effects.

An object of the invention is to enable various color effects to be produced as well as to produce motion effects simulating dancing.

Another object of the invention is to pro- 'duce a device capable of having the support for the shadow making bodies moved closer to or farther from the screen to increase or diminish the size or effect of the picture; and a further obj ect in conjunction with the same object is to move the position of the lights to change the effects.

Another object of the invention isto provide means whereby the person giving the performance may move from place to place over the screen without interfering with the exhibition.

Other objects of the invention will appear as the description proceeds.

An embodiment of the invention is shown in the drawings in which the same reference numeral is applied to thesame portion throughout, but I am aware that there may be modiiications thereof.

Figure 1 is a front elevation of the complete device showing ya portion of the front screen broken away for purposes of illustration, and

Fig. 2 is a side elevation of the apparatus with one side removed for purposesy of illustration, and with the front screen shown in vertical section. Y

The apparatus consists of three horizontal rectangular frames A, B, and C of which A is the base, while the frames B and C are supported by six posts 1 extending vertically above the base A, three on a side,

Suitable corner braces 2 are used to give the frame such rigidity as is necessary.

At the front of lthe frame, there is an opaque screen 3 extending from the base A to the frame B, while a translucent screen 4 is pivotally connected to the frame B just above the screen 3, and it extends to the The frame A supports two rails 12, 13,

while the frame B supports four rails 14 to 17 inclusive, and the frame C supports four rails 18 to 21 inclusive. The rails 12, 13, 14, 17 and 19, 21, support six wheels 22 to 28 inclusive which wheels carry a frame 29, on which frame are mounted a number of elec tric lights 30 each having a reflector 31.

The rails 15, 16 support two trucks 32, 33 which are connected by a bar 34 which serves to support any figures to be shown on the screen 4, and by means of which the figures may be moved to or from the screen.

The rails 19, 20 support wheels 35 36 (two at each side) which are connected with the bridge 37 on which the operator may stand.

'The bridge is stiffened with a truss rod 38 and post 39 to enable it to carry the necessary load.

In operation the workmen may walk into the front part of the frame under the bar 34, and the lights may be illuminated in any order desired, while at the same time a workman on the bridge 37 may let down suitable figures to cooperate with the figures placed on the bar 34 by the workmen below, strings or fine wires being used to lower the figures, to avoid shadows showing the supports for said figures. Other workmen may move the light carrying frame closer to the front screen if necessary.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is as follows, express reservation being made of permissible modifications:

1. A stage shadowgraph comprising a frame, a screen pivotally mounted therein, means to secure said screen in different angular adjustments in said frame, a figure support and lights for throwing a shadow from said figure on said screen.

2. A stage shadowgraph comprising a rectangular frame having a translucent screen therein, a movable figure support, a series of movable lights for throwing shadows upon the screen from the figures, and a movable bridge above the screen from vWhich other figures may be suspended at will.

3. A stage shadovvgraph Comprising a rectangular frame7 a pivotally supported trans'- lu'cent screen therein, means to support said screen in different angular adjustments, a movable support for gures adjacent the l0 screen,.a movable frame a series of lights carried by said frame for illuminating the screen and throwing shadows from said figures thereon7 and a movable bridge above the screen from which additional figures may be supportedV at will.

In testimony whereof I have hereunto s et my hand this 29th day of October 1 D. 1917. I
